FRUIT-JAR cLosUrm.

' Specification of Letters Patent. Patented Aug. 20, 1918.

Application filed August 8, 1917. Serial No. 185,013.

adjustable closure for fruit jars and is an improvement onfruit jarclosures such as are set forth in the patent of H. W. Putnam, No.256,857, April 25, 1882.

Considerable fruit is damaged through insecure closure of the jars inthe foregoing type of fruit jar. This is due to variation in thethickness of the rubber rings or gaskets, inequalities in'the wiresvcomprising the fastening means, and slack tension due to various causessuch, for instance, of wear, compression of the parts, bending of thewires, and lack of means to compensate, by adjustment, for thesedeficiencies as they arise.

My invention has forits object the provisibn of an improved tighteningorclosing means which can be quickly changed to enable any desired tensionto be put upon the clamping or locking bail so that a reserve of tensionis at all times obtainable to adapt the fastener to properly clamp theglass top or closure on the jar.

My invention docs'away with the defects heretofore existing in thisgeneral type of jar closures and renders it unnecessary to resort toextra rubber rings, pieces of card board or wood, or the like, to takeup the slack brought about by causes heretofore enumerated.

In carrying out my invention, I provide the neck of the fruit jar with aplurality of inclined shoulders, and a rotatable, or rotarily shiftableyoke or band having inclined parts or sections respectively adapted tocooperate with the inclined shoulders, the

clamping and operating bails being carried by the ring or yoke, wherebythe ring or yoke may be shifted to change, at will, the extremes orlimits of the vertical movement of the clamping bail so that the latterwill exert any desired tension on the closure when the. operating bailis pressed down. Preferably, the bails will be connected to clips orcars on the ring or yoke. If the ring or yoke is of wire, it will beprovided with crimps, humps or shoulders to retain the ears.

The jar is preferably provided with shoulders which oin the terminus ofone incline to the beginning of the next incline; and, the wire or yokewill. have shoulders or abutments which will be limited by the shouldersaforesaid to prevent too great backward movement of the yoke. The pointsof pivoting of the bails to the yoke are spaced apart by an arc of lesslength at one. side of the jar than at the other side so that thesepoints will not lie in the same diameter of the jar.

The embodiment of the invention which is hereinafter set forth and shownin the accompanying drawings is to be considered. as illustrative,instead of restrictive, of the scope of the invention; asmodificationsmay be resorted to without changing the principles of the invention.

In the accompanying drawings? Figures 1 and 2 are opposite side elevations; 7

Fig. 3, is a front elevation; gig. 1, is a section on line 44:, Fig. 3;3.11 a

Fig. 5, is a detail perspective of the band or yoke. I

The fruit jar 1 is provided with a groove or rabbet 2, a rubber ring orgasket 8, and a glass closure or top 1, as usual.

The neck is provided with a plurality, preferably two, cam inclines 5and 6.. The beginning or origination 7 of each incline is connected tothe terminus 8 of the other incline by a shoulder such as shown at 9 and10. The angle of inclination of theshoulders 5, 6 is the same. i

A band or yoke 11 encircles the neck of the jar and is rotatabletherearound, said band being provided with inclined portions 12 and 13respectively adapted to bear against the shoulders 5 and 6. The parts 12and 13 are connected by shoulders or bonds 14 and 15, respectivelyadapted to serve as abutments to engage the shoulders 9 and 10 to limitmovement of the band or yoke, backwardly. Ears or clips 16 and 17embrace the yoke or band and are held against slipping by the bends 18,in one instance, and by a bend 19 and the bent portion or shoulder 15,in the other instance. The clips are provided with holes 20, thedistance between the holes 20 of the respective ears or lugs is less,when measured along an are on one side of the jar than along an are onthe other side of the jar. The holes 20 are not at ends of a diameterbut are offset from a diameter. The operating bail 21 has its pivotalends 22 received in the holes 20 and it has bent eyes 23 which receivethe bent ends 2% of the locking bail 25. While the pivotal points of theoperating bail are offset from a diameter, the locking bail 25 lies indiametrical relation to the jar by reason of-the eyes 23 being thusdisposed. \Vhen clamping the closure down on the jar, the diametricallyoffset arrangement of -the pivots of the operating bail insures a firmlocking of the fastener, once the operating bail has been pressed down.

By shifting or rotating the band or yoke 11 around the neck of the jar,the holes 20 which represent the pivotal points of the bails, arebrought higheror lower, according to the direction in which the band oryoke is turned. This is brought about by the engagement of the parts 12and 13 with the cam inclines 5 and 6. Any desired tension can thereforebe arranged for. Consequently after use, if greater pressure or tensionis needed to hold the closure on the gasket the band or yoke is rotatedfurther and the locking bail will then properly hold the closure.

My invention provides for adjustment and reserve tension which takescare of inequalities due to manufacture and, also, to wear and existingconditions, insuring tight clo sure at all times.

I. am aware that a band could be substituted for the wire in which eventthe clips or cars might be an integral part of the band and there wouldbe no necessity for providing the retaining crimps or humps shown whichhold the clips against slipping.

Having thus described mv invention what I claim as new, and desire tosecure by Letters Patent, is

1. A fruit jar closure comprising a plurality of inclined cam shoulderson the jar, a yoke or band'rotatably mounted around the jar havinginclined parts corresponding to the shoulders and respectively adaptedto cooperatetherewith, and a releasable top fastener carried by saidyoke or band.

2. A fruit Jar closure comprising a plurality of inclined cam shoulderson the jar, r

abutments connecting the beginning of one shoulder with the terminus ofanother shoulder, a yoke or band rotatably mounted around the jar havinga plurality of inclined parts corresponding to, and cooperating with therespective cam shoulders, the band havto cooperate with them, and areleasable top fastener pivoted to the yoke or band in the-I.

region of the highest points of the inclined parts thereof.

4. A fruit jar closure comprising a plurality of inclined cam shoulderson vthe jar, a yoke or band rotatably mounted around the jar having aplurality of inclined parts corresponding to the shoulders and adaptedto cooperate with them, and a releasable top fastener pivoted to andcarried by said yoke or band at points on opposite sides of the jarwhich lie in a line of less length than a dianr eter, being nearer toeach other around one side of the jar than the other side of the jar.

5. A fruit closure comprising a plurality of inclined cam shoulders onthe jar, a yoke or band rotatably mounted around the jar having aplurality of inclined parts corresponding to the shoulders and adaptedto cooperate with them, an operating bail pivoted to the yoke or band atpoints offset from a diameter of the jar, and a locking bail adapted toengage the jar top, which is pivoted to the operating bail at pointsoffset;

from the pivots of the latter. In testimony whereof, I hereunto affix mysignature.
